Total Knee Replacement: From first visit to last Dr. Koss was very professional, informative, reassuring and helpful. Spent time to answer all questions and concerns. I am extremely happy with the results. 3 1/2 months after surgery, all goals are met - walking 3 miles, bowling well, and PAIN FREE ! Frankly, the only post-surgery pain was the range of motion PT activities, and occasional brief pain jabs with certain moves and these were gone after 3 months.

Hey there... Back in 1996/97 I fell and thought I just broke my leg. I had a visit with Dr. Koss and he explained my injuries were far more complicated. I can't remember all that was done, but I know it was extensive. Rehabilitation was grueling ,but it all payed off. 24 years later... my knee is still going strong. it is only in the last 2 years I have been in some pain due to arthritis. Kudos to Dr. Koss . Can't thank him enough. For anyone considering Dr. Koss for their surgery, I hope my review helps your decision! Sincerely, Kris Swanerbury

After quite a bit of pain and being unable to perform simple tasks around my home, I made the correct decision to have Dr. Koss perform surgery on my torn rotator cuff. After having just completed several months of physical therapy, I'm so pleased to have my shoulder back in great shape. Dr. Koss is an excellent surgeon, with a pleasant, calm manner. He answers all questions and takes the time to explain all procedures. He has my highest recommendation. We're so fortunate to have The Orthopedic Institute with its superior surgeons, professional staff, and excellent surgical center right here in Sussex County.

Dr. Koss operated on my ACL and did reconstructive surgery with a graph. I had a triad ligament tare which is the ACL, MCL and Meniscus from a skiing accident. He was able to explain what happened and what options I had. I decided on surgery which went very well. He is an excellent surgent and answers any questions you have. I never felt rushed or ignored when I asked questions. I am now out of physical therapy and working out in a gym going towards full recovery and being able to ski or do any sports I want. I am 55 so this truly great for me as I am very active person. Thanks Dr. Koss!

Dr. Koss did my knee replacement. He explained the procedure and answered any questions I had. He was very honest about what to expect after the surgery. I would recommend him to anyone who needs this surgery. If I should need it for my other knee in the future, I will definitely go to Dr. Koss to do it.

Diane M Krozser – Mar 10, 2021
He did my total knee replacement. I complained of no relief continually. He kept saying it tales at least a year. After a year I was able to go elsewhere for two other opinions. Both orthopedic surgeons said the wrong size insert was used and I need a complete revision surgery. Dr. Koss never even suggested that was the issue. Of course the wrong part shouldn’t have been used but I also shouldn’t have been poopooed for a year.

Dr. Koss solved two huge issues for me. He diagnosed a torn meniscus and performed an amazing repair that has given me a new lease on life. He also realized that the huge mass inside my thigh was a liposarcoma and immediately referred me to his friend and fellow surgeon who successfully removed the awful tumor. Dr. Koss is professional and humble and amazing. I should point out that the one-star review on this page was obviously an error in terms of clicking on the right number of stars because the description indicates only positive feedback. Even here, Dr. Koss offers a kind and humble response. Amazing Doctor! So thankful for Dr. Koss!

Daniel Hogan – Jul 29, 2020
I had previously seen Dr. Koss due to shoulder issues, which he was able to correct non-surgically. However, after suffering with a torn meniscus in my knee for 9 months, I decided to take his recommendation for arthroscopic surgical repair. So glad I did. I just completed the most pain-free surgery I've ever had and am already walking easily without meniscus pain. Dr. Koss should be at the top of everyone's list for orthopedic advice and surgery. I was well taken care of in all aspects of treatment - from his office staff to the surgical center - and am grateful for such incredible care.
